Her tweets were followed by a nine-minute video on YouTube that detailed her pregnancy.

This proved indeed that the Kardashians had been filming the pregnancy journey and we cannot begin to imagine the logistics of keeping the evidence hidden until now.

According to Mirror, everyone, from her employees, friends, family, and boyfriend Travis Scott, was involved in keeping it a secret.

A source close to the family said,

‘Keeping Kylie’s pregnancy under wraps for an entire nine months was ridiculously difficult for her friends. It was definitely a relief when they could finally congratulate her. It was the hardest secret to keep’.

One of the main cogs in the ‘secret’ machine was Kylie’s assistant Victoria Villarroel who was the first to know about the pregnancy.
